Strange pixelation/noise on low light processed photos

I have several low-light photos that show square areas of pixelation (noise) when processed as jpegs.  Each one has a hard line dividing the noise from the proper processing.  Some have a square grid across the image, where others just have one square area of noise.  This does not show when editing the image in the software and seems to only come out in processing.  I thought it was due to output sharpening, but I have this turned off.  Attached is an image as a sample.

  Here is another example.  Any thoughts?

  Try turning off hardware acceleration - this fixes all sorts of problems.
